A self-built Data Center Interconnect (DCI) provides several advantages:
✅High Efficient O&M – With self-built DCI, enterprises have full control over network monitoring, fault management, and performance optimization, reducing dependency on external providers.
✅Service Rollout on Time – Unlike leased lines, a self-built DCI network allows rapid service deployment without waiting for telecom operators, improving efficiency.
❌Guaranteed Quality – While a self-built network offers more control, it does not always guarantee quality compared to carrier-grade leased lines with SLAs (Service Level Agreements).
Thus, the correct answer is A and C.

Question 21
eSight can manage both IP and POL equipment in Campus OptiX solution.
eSight is Huawei’s network management system (NMS) designed to provide centralized management for various network elements. In the context of the Campus OptiX solution, HCSA-Sales-Transmission & Access documents confirm that eSight supports converged management of both IP-based equipment (e.g., switches, routers) and POL components (e.g., OLTs, ONUs). This capability enables unified monitoring, configuration, and fault detection across the hybrid IP+POL architecture, enhancing operational efficiency. The statement is consistent with eSight’s documented functionality, making it TRUE.
Huawei’s OLT family (SmartAX series) includes models like EA5800-X17, X7, X2, and others, totaling at least 4 variants, per HCSA-Sales-Transmission & Access, making A correct.
I passed my exam and achieved wonderful score, I highly recommend it.
